medial rectus muscle การใช้

• A fracture here could cause entrapment of the medial rectus muscle.
• Studies have provided indications that performing injections into both medial rectus muscles may be more effective than an injection into one medial rectus muscle alone.
• Studies have provided indications that performing injections into both medial rectus muscles may be more effective than an injection into one medial rectus muscle alone.
• This results in the failure of the medial rectus muscle to contract appropriately, so that the eyes do not move equally ( called disconjugate gaze ).
• In Graves ophthalmopathy, it is not uncommon to see an esotropia ( due to pathology of the medial rectus muscle ) co-morbid with a hypotropia ( due to pathology of the inferior rectus muscle ).
• Due to the accommodation to focus on a near object, an increase in the signal sent by cranial nerve III to the medial rectus muscles results, drawing the eyes inward; this is called the accommodation reflex.
• In normal vision, lateral movement of one eye ( lateral rectus muscle ) is precisely coupled to medial movement of the other eye ( medial rectus muscle ), so that both eyes remain fixed on the same object.
• The abducens nucleus contains two types of cells : motor neurons that control the lateral rectus muscle on the same side, and interneurons that cross the midline and connect to the contralateral oculomotor nucleus ( which controls the medial rectus muscle of the opposite eye ).
